BUCKLE FOB WRIST-WATCH STRAPS AND THE LIKE.

Application filed February 9, 1923. Serial No. 617,975.

To all whom it may concern:

Be it known that I, HERBERT, HARRY DUKE, a subject of the King of Great Britain, residing at 116 Lenton Boulevard,Nottingham, in England, have invented Improvements in Buckles for Wrist-l/Vatch Straps and the like, of which the following is a specification.

This invention relates to improvements in buckles for straps and has particular though not exclusive reference to buckles used on straps for wrist watches and the like.

The principal object of this invention is the provision of means for preventing a strap from becoming accidentally or inadvertently unbuckled and a further object amongst others is the provision of means for effectually covering the point of the buckle prong or tongue, where such tongue is provided.

The principal feature of the present invention consists in the provision of a movable or removable cover member which when the strap is in the fastened or buckled position is adapted to effectually prevent such strap from leaving the buckle prong or tongue and becoming unbuckled.

For the purpose of more fully describing the nature of this invention reference will now be made to the accompanying drawings, wherein Fig. 1 illustrates in plan a strap with buckle according to the present invention, such buckle being shown in the fully closed position.

Fig. 2 is a perspective view on an enlarged scale of the buckle shown in Fig. 1, the buckle cover being shown raised.

Fig. 8 illustrates in perspective a modified construction of buckle with cover opened.

Fig. 4: illustrates in perspective a further embodiment of the invention.

Fig. 5 is a detail section on line AA of F l, showing the spring removed.

Fig. 6 is a detail sectionon line A-A of Fig. i, showing spring in position.

In one embodiment of this invention as shown in Figs. 1 and 2 a cover member 1 is hingedly connected to the frame 2 of the buckle and is adapted when the strap 3 is fastened, to bear on or cover that portion of the strap 3 passing through the buckle, there being provided means for retaining the cover 1 in its placed position and means for rotating same to allow of the strap bemg unfastened. v p

Conveniently the frame 2 may be of rectangular configuration, one of the sides sides may be integral and a hole formed at the requisite position in two of said sides for the accommodation of the hinge pivot, such hinge after being assembled with the cover being retained in any suitable manner.

In the application of this invention to buckles furnished witha cross member 4 which carries the prong of tongue 5, the cover 1 may be hinged at the end of the tongue 5 when the strap 3 is fastened.

Alternatively if the tongue or prong is carried by an end member of the frame (as shown in Fig. 3) the cross bar 4 being provided, then the cover 1 may be conveniently hinged to one of the side members of the frame, such latter members being parallel with the length'of the strap.

F or the purpose of retaining the cover in its placed position when the strap is fastened projections may be conveniently formed on said cover 1 and such projections adapted to be accommodated within corresponding recesses in one of the frame sides. In the arrangement shown in Figs. 1 to 3 a lip 6 is formed on the cover 1 at that end remote from the hinge 7 and adapted to bear on that side 2 of the frameremote from said hinge, projections 8 of helm-spherical configuration being formed on said lip 6 and being accommodated within corresponding recesses 9 on said frame side 2 Manipulation of the cover is conveniently effected manually and a projection 10 is preferably formed on the lip 6 for enabling disengagement thereof with the frame 2.

The tongue or prong 5, or the point thereof is conveniently accommodated within a suitable recess 11 or the like formed in the cover 2.

In the modified arrangement shown in Figs. 4 to 6 inclusive, thatbar 2" of the frame 2 remote from the hinge 2 is formed on its front face with two elongated re cesses 12 (Fig. the outer end of each recess 12 being preferably deepened as at 13 these recesses being adapted to accommodate a spring having a bow shaped central portion 15 and small cranked ends 16, the latter enteringvthe deeper recesses 13. The spring iis retained in position by burring over the metal of the frame bar 2 at themouth of recesses 12. The hinge cover 1 is provided With ahbllowp'ro'jectioafi into which the spring 1% enters when the cover is closed so as to retain said cover in the closed position.

It will be appreciated that the buckle can be of variedsizes, and the shape thereof-mod ified inmany ways. Also, "a plurality of prongs5 may be incorporated. I

I am aware that prior to this invention it has been proposed to hingedly nount a cover member on buckle frames, siichcover haying flanges depending therefrom engaging with ing flange located at the, endreino-tefrom,

the hinge, saidflangeand one end,member of the frame each having co operating fastening means for retaining the cover in closed position.

2. In bucklesfo'r straps and the like, the combination of a buckle frame having a prong and a cover member hingedly mounted th'ereonfsaid ceifef' iiiember having a downwardly depending flange located at the extremity thereof opp osite'from the hinge, said flange having projections adapt-ed to engage recesses ino'ne "end bar of the frame and said cover having a recess for accommodating the Vpoin't; of the buckle prong,

In buckles for straps and the like, the combination T of a buckle frame having 1 a rong-and a 'coi er'member hingedly connected, thereon, said; coven member having a downwardly dependingliange, located at the end thereof remote from the hinge,,a curved spring, carried on theouter face'ofone end member. of. the 7 frame, saidfflange having a recess" 'for e ga ing" said; spring and, said cover h vi ga reeess for; accommodating the point of the buckle pron i HERBERT HARRY DUKE.
